Hi all, I have two Acer desktops that came with windows 8.1 core(oem) - factory installed. I want to reinstall the OS (bloat-ware). I'm hoping to recieve a factory pressed original win 8.1 pro DVD through the mail any day now. Is there some way to use this pro DVD, to reinstall core on both the desktops. (I would like to avoid downloading an iso, as the machines might be infected - thereby contaminating the iso). Really appreciate any help, members can contribute.
